232Vehicle careThis also applies to vehicles with tyrepressure monitoring system.
Unscrew the valve cap.
Tyre pressure 3 250.
The tyre pressure information label
on the left door frame indicates the
original equipment tyres and the
correspondent tyre pressures.
The tyre pressure data refers to cold
tyres. It applies to summer and winter tyres.
The ECO tyre pressure serves to
achieve the smallest amount of
energy consumption possible.
Incorrect tyre pressures will impair
safety, vehicle handling, comfort and
efficiency and will increase tyre wear.
Tyre pressures differ depending on
various options.
For the tyres approved for your
vehicle, refer to the EEC Certificate of
Conformity provided with your vehicle
or other national registration
documents.
The driver is responsible for correct
adjustment of tyre pressure.9 Warning
If the pressure is too low, this can
result in considerable tyre warm-
up and internal damage, leading to tread separation and even to tyre
blow-out at high speeds.
9 Warning
For specific tyres the
recommended tyre pressure as
shown in the tyre pressure table may exceed the maximum tyre
pressure as indicated on the tyre.
Never exceed the maximum tyre
pressure as indicated on the tyre.
If the tyre pressure must be reduced
or increased on a vehicle with tyre
pressure monitoring system, switch
off the vehicle.
Temperature dependency The tyre pressure depends on the
temperature of the tyre. During
driving, tyre temperature and
pressure increase. Tyre pressure
values provided on the tyre
information label and tyre pressure
chart are valid for cold tyres, which means at 20 °C.
The pressure increases by nearly
10 kPa for a 10 °C temperature
increase. This must be considered
when warm tyres are checked.
The tyre pressure value displayed in
the Driver Information Centre shows
the real tyre pressure. A cooled down
tyre will show a decreased value,
which does not indicate an air leak.
Vehicle care233Tyre pressure monitoringsystem
The tyre pressure monitoring system checks the pressure of all four tyres
once a minute when vehicle speed
exceeds a certain limit.Caution
Tyre pressure monitoring system
warns only about low tyre pressure condition and does not replace
regular tyre maintenance by the
driver.
All wheels must be equipped with pressure sensors and the tyres must
have the prescribed pressure.
Note
In countries where the tyre pressure
monitoring system is legally
required, the use of wheels without
pressure sensors will invalidate the
vehicle operating permit.
The current tyre pressures can be
shown in the Driver Information
Centre.
To access the tyre pressure page:
● Choose vehicle info menu via right steering wheel buttons and
press { or } to select tyre
pressure.
● Press 9 to select the tyre
pressure monitoring system.
System status and pressure warnings
are displayed by a message
indicating the corresponding tyre in the Driver Information Centre.
The system considers the tyre
temperature for the warnings.
Temperature dependency 3 231.
A detected low tyre pressure
condition is indicated by the control
indicator w 3 81.
If w illuminates, stop as soon as
possible and inflate the tyres as
recommended 3 250.
After inflating, some driving may be
required to update the tyre pressure
values in the Driver Information
Centre. During this time w may
illuminate.
If w illuminates at lower temperatures
and extinguishes after driving, this
could be an indicator for approaching
a low tyre pressure condition. Check
tyre pressure.
Vehicle messages 3 90.
If the tyre pressure must be reduced
or increased, switch off vehicle.
Vehicle care235The available settings are:● Light for comfort pressure up to
three people.
● Eco for Eco pressure up to three
people.
● Max for full loading.
Auto learn function Each tyre pressure sensor has a
unique identification code. The
identification code must be matched
to a new wheel position after rotating
the wheels or exchanging the
complete wheel set and if one or more tyre pressure sensors were replaced.
After changing wheels, the vehicle
must be stationary for approx.
20 minutes before the system
recalculates. The following relearn
process takes up to 10 minutes of
driving with a minimum speed of
20 km/h. In this event, w can be
displayed or pressure values can
swap in the Driver Information Centre.
If problems occur during the relearn
process, a warning message will be
displayed in the Driver Information
Centre.Tread depth
Check tread depth at regular
intervals.
Tyres should be replaced for safety
reasons at a tread depth of 2-3 mm
(4 mm for winter tyres).
For safety reasons it is recommended
that the tread depth of the tyres on
one axle should not vary by more than 2 mm.
The legally permissible minimum
tread depth (1.6 mm) has been
reached when the tread has worn
down as far as one of the tread wear
indicators (TWI). Their position is
indicated by markings on the
sidewall.
If there is more wear at the front than
the rear, swap round front wheels and rear wheels periodically. Ensure that
the direction of rotation of the wheels
remains the same.
Tyres age, even if they are not used.
We recommend tyre replacement
every six years.
Changing tyre and wheel size
If tyres of a different size than those
fitted at the factory are used, vehicle
performance, including braking, ride
and handling characteristics, stability
and resistance to rollover may be
affected. If the vehicle has electronic
systems such as antilock brakes,
rollover airbags, traction control,
electronic stability control, the
performance of these systems can
also be affected. It may be necessary
to reprogramme the speedometer as
well as the nominal tyre pressure and
make other vehicle modifications.
242Vehicle careUnderbody
Some areas of the vehicle underbody
have a PVC undercoating while other critical areas have a durable
protective wax coating.
After the underbody is washed, check
the underbody and have it waxed if
necessary.
Bitumen/rubber materials could
damage the PVC coating. Have
underbody work carried out by a
workshop.
Before and after winter, wash the
underbody and have the protective
wax coating checked.
Interior care
Interior and upholstery Only clean the vehicle interior,
including the instrument panel fascia
and panelling, with a dry cloth or
interior cleaner.
Clean the leather upholstery with
clear water and a soft cloth. In case of
heavy soiling, use leather care.The instrument cluster and the
displays should only be cleaned using
a soft damp cloth. If necessary use a
weak soap solution.
Do not spray cleaners directly on any switches or controls.
Clean fabric upholstery with a
vacuum cleaner and brush. Remove
stains with an upholstery cleaner.
Clothing fabrics may not be
colourfast. This could cause visible
discolourations, especially on light-
coloured upholstery. Removable
stains and discolourations should be
cleaned as soon as possible.
Clean seat belts with lukewarm water or interior cleaner.Caution
Close Velcro fasteners as open
Velcro fasteners on clothing could damage seat upholstery.
The same applies to clothing with
sharp-edged objects, like zips or
belts or studded jeans.
Plastic and rubber parts
Plastic and rubber parts can be
cleaned with the same cleaner as
used to clean the body. Use interior cleaner if necessary. Do not use any
other agent. Avoid solvents and petrol in particular. Do not use high-
pressure jet cleaners.
